Juno

A simple "Workflow" service utility belt.

Installation

Add this line to your application's Gemfile:

gem 'Juno', github: "RepPro/Juno"

And then execute:

$ bundle

Or install it yourself as:

$ gem install Juno

Usage

Juno current provides two composable utilties.

###Juno.active_record

Provides a single helper, transact!, to deal with active record transactions and handling failure.

class Create
  include Juno.active_record

  def call
    transact! {@user.create!(name: "James Brown")}
  end
end

Transact will wrap the passed in block in an ActiveRecord::Base.transaction and rescue the exception. That exception will then be pushed into a @errors ivar.

###Juno.service

Provides a set of helpers to construct workflows.

class Create
  include Juno.service

  def call
    do_something
  end
end

By including Juno.service you will get the following:

1. A .call class method with wildcard arity that will instantiate your class and pass all args to your call method.
2. attr_reader for params and errors
3. A _params method to unwrap your params if they are still an instance of StrongParams.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
